NORFOLK, Va. (AP) Norfolk State's athletic department will vacate 97 victories and three conference championships and spend two years on probation after an NCAA investigation that found the school allowed 48 ineligible student-athletes to compete over a period of four academic years.

The school and the NCAA's Division I Committee on Infractions announced the decision Thursday.

The violations were discovered by the school after the 2011-12 academic year and reported to the NCAA. The school also self-imposed penalties, including a $5,000 fine. The NCAA report stated the university also imposed ''meaningful corrective measures and penalties.''
